NV Motorsport built this BMW E46 318i called “Silver Surfer” at their company in the UK. The wagon came with a 2.0 L inline-four making 140 hp. NV Motorsport wanted a lot more so they swapped a 3.0 L B58 inline-six from a wrecked BMW M140i. They fabricated custom mounts and might eventually sell them in a swap kit. Behind the B58 is a Spec clutch and six-speed manual transmission. A modified BMW driveshaft turns the factory rear differential. To help control the extra power they installed Tarox eight-piston brakes in front and six-piston brakes in back. Those are covered by Titan T-R10 wheels with Nankang CR-S tires. You can watch the project’s progress in the build playlist.
